Here's the deal. I press the lock or unlock buttons in my car and now only the pass. side door locks and unlocks. Nothing is happening on the drivers side. Any ideas what this could be or where I should start looking? Thanks.

 

Looking at the wiring diagram. It appears that the same relay activates the door lock actuators on both doors. Can anyone verify this?

And if so, that must mean that it is the door lock actuator that is bad, correct?

 

Yes there is only one relay and it operates both door locks. Have you pulled the door panel off and looked at the connection for the driver side actuator? Have you had the driver side door panel off doing anything. Also check the wiring at the switches on the doors to see if one wire might be broken.

 

No, I havent had the door panel off in about 2 yrs. It happened overnight. I have remote door locks and an alarm. I tried opening the doors with the remote and the drivers side didnt do anything and it was still locked, meaning that something happened after the alarm locked the door after the last time I closed it.

I will pull the door panel to inspect things as soon as I get a chance, but the switches on both doors still lock/unlock the pass. side door.
